CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of the U.S. application Ser. No. 16/554,611, filed Aug. 28, 2019, which is a continuation of International Application No. PCT/CN2017/105190, filed Oct. 1, 2017, claiming the priority benefit of Chinese Patent Application Serial Number 201710161931.3, filed on Mar. 17, 2017, the full disclosure of which is incorporated herein by reference.

BACKGROUND Technical Field

The present disclosure relates to transmission methods and devices for radio signals in wireless communication systems, and in particular to a transmission scheme and device for radio signals in a wireless communication system that supports uplink control information transmission.

Related Art

In traditional Long Term Evolution (LTE) systems, when a User Equipment (UE) is required to transmit uplink control information (UCI) and uplink data simultaneously on a sub-frame, UCI can be transmitted together with data on an uplink physical layer data channel. A number of Resource Elements (REs) occupied by UCI on the uplink physical layer data channel is related to a Modulation and Coding Scheme (MCS) employed in a first transmission of uplink data. Since the MCS of uplink data reflects the channel quality of an uplink channel, the method ensures transmission reliability of UCI on an uplink physical layer data channel.

SUMMARY

Compared with traditional LTE systems, 5G systems will support more diversified application scenarios, such as enhanced Mobile BroadBand (eMBB), Ultra-Reliable and Low Latency Communications (URLLC) and massive Machine-Type Communications (mMTC). Different application scenarios may have varying requirements for transmission reliability on a physical layer, and the gap between these requirements may be more than one order of magnitude on some occasions. Inventors have found through researches that if technologies in existing LTE systems continue to be applied, transmission reliability of UCI will vary from one application scenario to another when multiplexed with uplink data, which will probably cause wastes of uplink radio resources in some cases.

Inventors also have found through researches that in a system using multi-antenna beamforming, when different beamforming vectors are employed in a first transmission and a retransmission, there will be large distinction between uplink channel qualities respectively corresponding to the first transmission and retransmission. According to technologies in existing LTE systems, the number of REs occupied by UCI is always related to MCS of the first transmission. When UCI is multiplexed with retransmitted uplink data, and a beamforming vector employed in retransmission is different from that in first transmission, it will be hard to guarantee UCI transmission quality.

In view of the above problem, the present disclosure provides a solution. It should be noted that if no conflict is incurred, the embodiments in a UE of the present disclosure and the characteristics in the embodiments may be applied to a base station, and vice versa.

When UCI is multiplexed with uplink data in various application scenarios, whatever the physical layer transmission reliability of uplink data is, a base station will be able to ensure the stability of UCI transmission reliability by changing the offset between UCI transmission rate and MCS of uplink data.

When UCI is multiplexed with retransmitted uplink data and a channel for retransmission does not match with a channel for the first transmission, a base station will be able to ensure sufficiently high UCI transmission reliability by changing the offset between UCI transmission rate and MCS of uplink data.

The offset between UCI transmission rate and MCS of uplink data is jointly determined by a higher-layer signaling and a physical layer signaling, therefore, transmission reliability of UCI can be controlled flexibly and excessive physical layer signaling overhead can be avoided.

EMBODIMENT 12

Embodiment 12 illustrates a schematic diagram of an embodiment of a radio protocol architecture of a user plane and a control plane, as shown in FIG. 12.

FIG. 12 is a schematic diagram illustrating a radio protocol architecture of a user plane and a control plane. In FIG. 12, the radio protocol architecture for a UE and a gNB is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY 1201 in the present disclosure. The layer 2 (L2) 1205 is above the PHY 1201, and is in charge of the link between the UE and the gNB via the PHY 1201. In the user plane, L2 1205 comprises a Medium Access Control (MAC) sublayer 1202, a Radio Link Control (RLC) sublayer 1203 and a Packet Data Convergence Protocol (PDCP) sublayer 1204. All the three sublayers terminate at the gNBs of the network side. Although not described in FIG. 12, the UE may comprise several protocol layers above the L2 1205, such as a network layer (i.e., IP layer) terminated at a P-GW 1113 of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.). The PDCP sublayer 1204 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 1204 also provides a header compression for a higher-layer packet so as to reduce a radio transmission overhead. The PDCP sublayer 1204 provides security by encrypting a packet and provides support for UE handover between gNBs. The RLC sublayer 1203 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a packet so as to compensate the disordered receiving caused by Hybrid Automatic Repeat reQuest (HARQ). The MAC sublayer 1202 provides multiplexing between a logical channel and a transport channel. The MAC sublayer 1202 is also responsible for allocating between UEs various radio resources (i.e., resource block) in a cell. The MAC sublayer 1202 is also in charge of HARQ operation. In the control plane, the radio protocol architecture of the UE and the gNB is almost the same as the radio protocol architecture in the user plane on the PHY 1201 and the L2 1205, but there is no header compression for the control plane. The control plane also comprises a Radio Resource Control (RRC) sublayer 1206 in the layer 3 (L3). The RRC sublayer 1206 is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the gNB and the UE.

EMBODIMENT 13

Embodiment 13 illustrates a schematic diagram of a New Radio (NR) node and a UE, as shown in FIG. 13. FIG. 13 is a block diagram illustrating a UE 1350 and a gNB 1310 that are in communication with each other in access network.

The gNB 1310 comprises a controller/processor 1375, a memory 1376, a receiving processor 1370, a transmitting processor 1316, a multi-antenna receiving processor 1372, a multi-antenna transmitting processor 1371, a transmitter/receiver 1318 and an antenna 1320.

The UE 1350 comprises a controller/processor 1359, a memory 1360, a data source 1367, a transmitting processor 1368, a receiving processor 1356, a multi-antenna transmitting processor 1357, a multi-antenna receiving processor 1358, a transmitter/receiver 1354 and an antenna 1352.

In downlink (DL) transmission, at the gNB 1310, a higher-layer packet from a core network is provided to the controller/processor 1375. The controller/processor 1375 provides a function of the L2 layer. In DL transmission, the controller/processor 1375 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation for the UE 1350 based on various priorities. The controller/processor 1375 is also in charge of HARQ operation, retransmission of a lost packet, and a signaling to the UE 1350. The transmitting processor 1316 and the multi-antenna transmitting processor perform signal processing functions used for the L1 layer (that is, PHY). The transmitting processor 1316 performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the UE 1350 side and implements the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmitting processor 1371 performs digital spatial precoding/beamforming on encoded and modulated symbols to generate one or more spatial streams. The transmitting processor 1316 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. After that the multi-antenna transmitting processor 1371 performs transmission analog precoding/beamforming operation on the time-domain multi-carrier symbol streams. Each transmitter 1318 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 1371 into a radio frequency (RF) stream, which is later provided to different antennas 420.

In downlink (DL) transmission, at the UE 1350, each receiver 1354 receives a signal via a corresponding antenna 1352. Each receiver 1354 recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 1356. The receiving processor 1356 and the multi-antenna receiving processor 1358 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 1358 perform reception analog precoding/beamforming operation on the baseband multicarrier symbol stream provided by the receiver 1354. The receiving processor 1356 converts the baseband multicarrier symbol stream from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 1356, wherein a reference signal is used for channel estimation, while physical layer data is subjected to multi-antenna detection in the multi-antenna receiving processor 1358 to recover any UE 1350-targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor 1356 to generate a soft decision. Then the channel decoder 1358 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the gNB 1310. Next, the higher-layer data and control signal are provided to the controller/processor 1359. The controller/processor 1359 performs functions of the L2 layer. The controller/processor 1359 can be connected to a memory 1360 that stores program code and data. The memory 1360 can be called a computer readable medium. In downlink transmission, the controller/processor 1359 provides demultiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing. The controller/processor 1359 also performs error detection using ACK and/or NACK protocols as a way to support HARQ operation.

In uplink (UL) transmission, at the UE 1350, the data source 1367 is configured to provide a higher-layer packet to the controller/processor 1359. The data source 1367 represents all protocol layers above the L2 layer. Similar to a transmitting function of the gNB 1310 described in DL transmission, the controller/processor 1359 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the gNB 1310 so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 1359 is also responsible for HARQ operation, retransmission of a lost packet, and a signaling to the gNB 1310. The transmitting processor 1368 performs modulation mapping and channel coding, and the multi-antenna transmitting processor 1357 performs digital multi-antenna spatial precoding/beamforming. The generated spatial streams are modulated into multicarrier/single-carrier symbol streams by the transmitting processor 1368, and then modulated symbol streams are subjected to analog precoding/beamforming in the multi-antenna transmitting processor 1357 and are provided from the transmitters 1354 to each antenna 1352. Each transmitter 1354 first converts a baseband symbol stream provided by the multi-antenna transmitting processor 1357 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 1352.

In uplink (UL) transmission, the function of the gNB 1310 is similar to the receiving function of the UE 1350 described in DL transmission. Each receiver 1318 receives a radio frequency signal via a corresponding antenna 1320, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 1372 and the receiving processor 1370. The receiving processor 1370 and the multi-antenna receiving processor 1372 jointly provide functions of the L1 layer. The controller/processor 1375 provides functions of the L2 layer. The controller/processor 1375 can be connected with the memory 1376 that stores program code and data. The memory 1376 can be called a computer readable medium. In UL transmission, the controller/processor 1375 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the UE 1350. The higher-layer packet coming from the controller/processor 1375 may be provided to the core network. The controller/processor 1375 can also perform error detection using ACK and/or NACK protocols to support HARQ operation.
